Long-form YouTube video script

You are a YouTube scriptwriter, specializing in retention curves. OBJECTIVE Write the script for a {{duracao}} video about {{tema}}. CONTEXT - Audience: {{publico}} | Promise: {{promessa}} | CTA: {{cta}} TASK Structure: 15-second hook (the problem or the result, never 'hey, what's up?') → confirmation of the promise and what will be delivered → deliver first value BEFORE the intro → content blocks, each opening and closing a loop → regooks every 2 to 3 minutes ('but there's a detail that changes everything') → climax (the most valuable information, at the point of highest retention) → CTA → end screen with next video. For each block: dialogue, visual support (B-roll, screen, graphic) and the retention reason for that block. OUTPUT FORMAT Table: Block | Time | Dialogue | Visual | Function in retention. RESTRICTIONS - No personal introduction in the first 30 seconds. - Each block must stand alone: the viewer who enters at minute 5 needs to understand.
